Definitions

  • the invention relates to a fixing support for anchoring the supporting frame of a sanitary facility, in particular of a toilet, bidet, washbasin, shower and urinal, to the masonry, which comprises a connecting pin adapted to be inserted into the supporting frame and to be secured in the supporting frame, the connecting pin being coupled to an anchor screw for fixing to the masonry.
  • a solution of a fixing support which comprises a plastic bolt with a head with an inner hexagon, whereby assigned to this bolt is a box-shaped elongated body "L", which is provided with a longitudinal through hole with a partial thread, in which an eccentric nut with an internal thread for said bolt is rotatably mounted about a longitudinal axis.
  • the screw In one position of rotation of this nut, the screw is movable linearly in the longitudinal axis of the hole even without its rotation, while in another rotated position of this nut, the partial thread in the rotating nut and the thread on the bolt interlock, so that the bolt can be moved merely by rotary motion.
  • the disadvantages of this embodiment include the complexity of using a rotating nut with a partial thread, the relatively large dimensions of the box-like elongated body and the presence of the plastic bolt, which together constitute a system with limited strength and stability.
  • a solution of a fixing support which comprises a metal screw with a markedly shaped fixing attachment forming the head of this screw, whereby a metal housing with a partial internal thread is assigned to the screw, this housing being open from one end to insert the screw into the housing.
  • a safety ring is threaded on the housing.
  • the safety ring is provided in its inner hole with a longitudinal protrusion for pushing the thread on the screw into the thread in the housing by moving the safety ring on the housing in the direction longitudinal to the housing and the screw.
  • the other end of the housing is provided with an extension in the form of a collar or flat head, etc., whereby assigned to this end of the housing with the extension is a plug which is intended to be inserted into the end of the profile of the fixed frame.
  • the fixing support also attaches to the frame, which is thus better fixed to the masonry.
  • the disadvantages of this configuration include the relative complexity of the solution, production demands and material diversity.
  • the object of the invention is to eliminate or at least minimize the disadvantages of the background art.
  • the object of the invention is achieved by a fixing support for anchoring a supporting frame of a sanitary facility, in particular of a toilet, bidet, washbasin, shower and urinal, to the masonry, whose principle consists in that the connecting pin is is provided at its rear end with a longitudinal split nut, which passes through the cavity of a nut lock and which is provided on its inner side with nut sections with parts of a nut thread, into which fits the outer thread on the shank of the anchor screw, whereby the nut lock is reversibly displaceable in the direction of the length of the split nut and the split nut is provided on its outer surface with inclined surfaces adapted to control the clamping of the split nut around the screw.
  • the advantage of the present invention is its simplicity, reliability and ease of installation and use.
  • the split nut comprises a pair of opposed longitudinal half-nuts which are resiliently connected to the rear end of the connecting pin by their front ends, whereby the two half-nuts are separated from each other by a longitudinal gap and each half-nut comprises on its part adjacent to the opposite half-nut one nut section with a part of a nut thread.
  • the nut sections on one half-nut are arranged outside the mutually direct opposite direction relative to the nut sections on the other half-nut.
  • the inclined surfaces have a height which gradually increases from zero at the front end of the split nut at the connecting pin towards the rear end of the split nut, so that in the position of the nut lock at the connecting pin there is a gap between the inner surface of the nut lock hole and the outer surface of the split nut, the gap serving to open the split nut and to allow the anchor screw to slide longitudinally in the split nut even without rotating, whereby in the position of the nut lock at the rear end of the split nut, the inner surface of the nut lock hole presses the nut sections of the split nut against the outer thread on the shank of the anchor screw to allow merely rotation of the anchor screw.
  • the anchor screw For anchoring to the wall, the anchor screw has a bent foot with a through hole at its rear end.
  • the connecting pin is provided with at least one collar and/or a circumferential groove corresponding to at least one shaped protrusion and/or a groove on the front of the locking insert adapted to be inserted into the beam of the supporting frame.
  • Fig. 1 shows a pre-wall WC module with fixing supports according to the invention
  • Fig. 2 shows a detail of the a pre-wall WC module with the fixing support according to the invention
  • Fig. 3 shows an exploded view of the arrangement of the fixing support of Fig. 2
  • Fig. 4 shows a detail of a locking insert
  • Fig. 4a shows a detail of a nut lock
  • Fig. 4b shows a longitudinal section through the nut lock
  • Fig. 4c shows a detail of a screw
  • Fig. 5 shows a detail of a connecting pin with a split nut
  • Fig. 6 shows a longitudinal section through the connecting pin with the split nut of Fig. 5
  • Fig. 7 shows a longitudinal section through the fixing support with the split nut before the screw insertion
  • Fig. 8 shows a longitudinal section through the fixing support with a closed split nut and with the inserted screw.
  • the invention will be described with reference to an exemplary embodiment of a fixing support 1 for anchoring a supporting frame 2 of a WC module to masonry, whereby it is obvious that the details, parts, principles and functions described below are adequately applied also to a fixing support for anchoring a supporting frame of another sanitary device to masonry, especially for anchoring the supporting frame of bidets, washbasins, showers, urinals, etc.
  • a through hole 200 is formed in a beam 20 of the supporting frame 2 , the through hole 200 being adapted for insertion of a connecting pin 10 of the fixing support 1 into the inner space of the beam 20.
  • the connecting pin 10 in the inner space of the beam 20 is secured against spontaneous ejection from the hole 200, e.g., by means of a locking insert 11, which is adapted to be inserted into an open end 201 of the beam 2 and for securing the connecting pin 10 against spontaneous ejection from the hole 200 in the beam 20.
  • the connecting pin 10 is, for example, provided with at least one, but ideally, with at least two collars 100 and/or circumferential grooves 101, into which, in the state of being inserted in the beam 20, shaped intrusions 1101 and/or grooves 1101 on the front 110 of the locking insert 11 fit, as shown in Fig. 4 .
  • the locking insert 11 prevents the connecting pin 10 from sliding out in the direction of its longitudinal axis from the beam 20 of the supporting frame 2.
  • the locking insert 11 provides a pivotal mounting of the connecting pin 10 in the beam 20 of the supporting frame to allow precise adjustment of the distance of the supporting frame 2 from the vertical wall to which the supporting frame 2 is fixed.
  • a longitudinal split nut 12 which comprises a pair of half-nuts 120 arranged opposite each other, which are by their front ends resiliently connected to the rear end of the connecting pin 10.
  • the two half-nuts 120 are separated from each other by a longitudinal gap M, whereby each half-nut 120 comprises on its inner part, i.e. on the part adjacent to the opposite half-nut 120, at least one nut section 1200 with a part 12000 of a nut thread (nut comb).
  • the nut sections 1200 on one half-nut 120 are arranged outside a mutually opposite direction relative to the nut sections 1200 on the other half-nut 120, see Fig.
  • the two half-nuts 120 of the split nut 12 pass together through the cavity of the nut lock 14, which is mounted on the split nut 12 reversibly displaceable in the direction of the length of the split nut 12, and whereby the split nut 12, or the half-nuts 120, is/are provided on its/their outer surface/s with inclined ramps 1201 , whose height increases gradually from zero at the front end of the split nut 12 at the connecting pin 10 towards the rear end of the split nut 12, and so in the position of the nut lock 14 at the connecting pin 10, see Fig.
  • the inner surface of the hole of the nut lock 14 presses the two half-nuts 120 through their nut sections 1200 via the inclined ramps 1201 against the outer thread 130 on the shank 131 of the anchor screw 1 described below, whereby the anchor screw 13 can be moved in the split nut 12 merely by rotation, even with a certain increased resistance due to the pressure of the half-nuts 120 on the shank 131 of the screw 13.
  • the level of the pressure of the nut sections 1200 of the half-nuts 120 on the outer thread 130 on the shank 131 of the anchor screw 13 and the transition between the free longitudinal displacement of the screw 13 and the mere rotation of the screw 13 can be regulated to some extent by the position of the nut lock 14 along the length of the split nut 12.
  • the nut lock 14 controls the clamping of the split nut 12, or of the half-nuts 120, around the screw 13.
  • the screw 13 is at its rear end provided with a bent foot 132 with a through hole 1320 for anchoring to the wall.
  • the invention is particularly applicable in the construction industry for anchoring supporting frames of sanitary installations to masonry, such as the supporting frames of toilet modules, bidets, washbasins, showers, urinals, etc.
